SPECIFICATION forming part of Letters Patent No. 786,587, dated April 4, 1905.

Application filed January 10, 1905. Serial No. 240,445.

7'0 u/ZZ III/1,0772, it rnctz concern:

Be it known that we, EVELYN O. MORGAN and FANNIE B. OSTROM, citizens of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Tray-Supports, of which the following is a specification.

Our invention is an adjustable support adapted for supporting platforms or for other uses; and it consists of two members, one adjustable upon the other and each provided with shoulders engaging shoulders of the other, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which- Figure 1 is an elevation illustrating one form in which our support may be made. Fig. 2 is an edge view of the construction shown in Fig. 1. Fig. 3 is a perspective view showing a series of supports applied to a platform. Fig. 4 is a view of the support constructed to form a spring-clip for engaging the platform. Fig. 5 is a plan View showing supports, such as shown in Fig. 4, applied to a circular platform.

The support consists, essentially. of two members A B. The member A is provided with two parallel rods 1 1, which may constitute parts of a frame of any suitable construction, but are, as shown, parts of asingle wire bent to form the said rods with a connecting part which may be of any suitable shape, but which is preferably formed into a clip C, being so bent as to form a mouth a, Fig. 2, into which may be introduced the edge of a plate or platform X, of any suitable character, which is to be supported in whole or in part by the device.

Preferably the part is a spring-clip consisting of a V-shaped portion of the wire 3, Fig. 5, overhanging and pressing with a springpressure upon horizontal sections of the wire which connect with the rods 1 1, so that when the platform or plate X is passed into the mouth between the parts 3 and i it will be firmly clasped and the device will be fixedly secured to the plate or platform.

At the lower end of each rod 1 is a shoulder 6, preferably formed by bending the end of the wire outward into an eye or loop into which can pass the legs 7 7 of the other member, B, which member, as shown, is a wire of a general U shape and having a cross-piece 8, connecting the legs 7 7 and bent to form ears 9, through each of which passes one of the rods 1.

Each leg 7 is bent to form a series of shoulders 10, and this member B is so constructed that the legs tend to spring apart after the two members have been brought together, so that each leg 7 will bear with an outward pressure against the shoulder 6 of the other member. This permits the member B to be set and secured in different positions upon the member A, it being only necessary to bring toward each other the legs 7 7 and then slide the member B upon the member A to any desired position, when upon releasing the legs they will spring outward and the shoulders 6 of the member A will rest upon the shoulders of the member B, thereby preventing any downward movement of the member A.

Preferably the lower ends of the legs 7 are bent outward to form eyes or feet 12.

In the construction shown in Figs. 1, 2, 3, and 4 the clip 0 is not a spring-clip, and in Figs. 3 and 4 the platform X is in the form of a wire frame, to the corners of which the adjustable support may be secured, as best shown in Fig. 3. In Fig. the clip is shown as a spring-clip engaging the edge of a circular disk or platform X. Vhile the structure is preferably formed of wire, as described, this is not essential, as it may be otherwise made.

Without limiting ourselves to the precise construction and arrangement of parts shown, we claim* 1. In an adjustable support, the combination of two members, one sliding on the other and provided with spring shouldered legs adapted to engage shoulders of the other, substantially as set forth.

2. The combination in an adjustable sup-- port, of a member having parallel rods with shoulders at the ends thereof, and a member engagingand sliding on said rods, with spring legs each having a series of shoulders adapted to engage the shoulders of the other member, substantially as set forth.

3. The combination in an adjustable sup port, of a member having parallel rods, a clip at one end thereof, and a shoulder at the other end of each rod, and a sliding spring memher having eyes for the passage of said rods and two legs each with a series of shoulders, substantially as set forth.

4. The combination in an adjustable support, of a member having parallel rods, a clip at one end thereof adapted to receive the edge of a plate or platform, and a shoulder at the other end of each rod, and a sliding spring member having eyes for the passage of said. rods and two legs each with a series of shoul ders, substantially as set forth.

5. The combination in an adjustable support, of a membe having parallel rods, a spring-clip at one end thereof adapted to re ceive the edge of a plate or platform, and a shoulder at the other end of each rod, and a slidii'ig spring member having eyes for the passage of said rods and two legs each with a series of shoulders, substantially as set forth.

6. The combination in an adjustable support, of a member having a cross-piece and two legs connectet to thecross-pieee to spring apart when brought toward each other, each leg with. a series of shoulders, and a member with parallel rods constituting guides for the other member and with shoulders at the ends engaging those of the spring member, substantially as set forth.

7. The combination in an adjustable support, of two members, one consisting of wire bent to form a cross-piece, two parallel rods, and a loop or eye at the end of each rod, the other member of wire bent to form a crosspiece, two eyes, one receiving each of said rods to be guided thereby, and two spring-legs each with a series of shoulders, substantially as set forth.

8. The combination in an adjustable support, of two members, one consisting of wire bent to form a cross-piece constructed to constitute a clip, two parallel rods, and a loop or eye at the end of each rod, the other member of wire bent to form a cross-piece, two eyes, one receiving each of said rods to be guided thereby, and two spring-legs each with a series of shoulders, substantially as set forth.

9. The combination in an adjustable support, of aplatform, and a plurality of legs each consisting of two members, one with a clip to receive the edge of the platform and with rods having shoulders at the ends thereof, the other sliding on said rods and provided with spring-legs having shoulders adapted to engage the shoulders of the other member, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
